Said headerunit'is mounted upon a suitable ATENTOFFICE supporting frame, which is shown as comprising' 5 vertical frame members 9 and horizontal `iframe members II, I2, and I3, Said header maybe se-v cured to and supported upon the supporting frame in any suitable manner, as by means of or the like, rigidly connected to said header and to saidV supporting frame. n

The multiple-cyclone separating unit 2 conllprises a pluralityof vertically elongated tubular I4 consistingl of angle bars 1o cyclone elementslS of circular cross-section and l5 l relatively small diameter, mounted directly below the `gas inlet chamber 4 "andconnected together toform a single structural unit. Each of said tubular elements is shown as provided at its upper end ,with sloping side wall portions I1, forming a rectangular opening `I l and the upper` edges of the several elements are secured together in any rsuitable manner, Las." indicated at I9.

The "assembled groupof` cyclone elements is 25 the upper ends thereof communicating with the and means are provided for" header unit I, while permitting said'units to be quickly and easily disconnected from one'another. For this purpose, quick-detachable connecting meanssuch as cclamps maybe provided for clampat 23,` and it will be. understood that any clamps may be at intervals along'theseveral sides of theappa- -ratus` Afsuitable gasket mayV be providedbetween the angle bars I4 and 22, to prevent leakinternal diameter of vthe tubular cyclone ele- `sages 21 therebetween, whichcommunicate with the inlet Vchamber 4.

e The tubes 26, which serve as gas outlet passages for the respective cyclone elements I 6; extend upwardly through the inlet chamber 4, and communicate at their upper ends 55V normally supported as a vunit,in position with provided 40 ments, so as to provide annular gas inlet pas- 5o 8 at the upper end thereof, 20

with the outlet chamber 5. The upper end portions of said outlet tubes may be formed similarly to the upper end portions of the tubular cyclone elements, as above described, and the upper edges thereof are connected together as shown at 28, and are also connected to the side walls 8 of the header unit I, so as to remain connected with said header unit when the cyclone unit 2 is separated therefrom, as hereinafter described. The interconnected upper end portions of said gas outlet tubes serve to separate the gas inlet chamber 4 from the gas outlet chamber 5.

Means are provided forl producing swirling movement of the gas passing from the inlet chamber 4- into the respective tubular cyclone elements I6. For this purpose, an annular series of helically inclined vanes 3I may be mounted in the annular passages between the lower end portions of the gas outlet ends 26 and the cyclone elements, and said vanes are preferably mounted on said gas outlet tubes, as clearly shown in Fig. 5.

The several cyclone elements I6'open at their lower ends into the material collecting unit 3, as shown for example at 33, and the lower end portions of said elements are preferably tapered in a downward direction as indicated at 34, so that the openings 33 are of smaller diameter than the main portion of the cyclone elements, providing restricted centrally disposed dust outlet openings.

The material collecting unit 3 comprises a chamber or hopper preferably provided with downwardly and' inwardly inclined side walls 35, and any suitable means may be provided for continuous or intermittent discharge of collected material through an opening at the bottom of said chamber asat 32.

A horizontal plate 36 secured to and around the lower ends of the cyclone elements I6 serves to normally close the upper end of the collecting chamber 3 and prevent communication of said chamber with the exterior, while permitting free communication of said chamber with the interior of the cyclone units. Re-enforcing bars 39 may be provided at the edges of said plate 36. The material collecting unit 3 is also connected to the cyclone unit 2 by quick-detachable connecting means. For this purpose, I may provide angle bars 31 or the like, extending around the four sides of the chamber 3 at the upper edge thereof, and any suitable number of quick-detachable connecting'devices, such as C-clamps, may be provided for normally securing said angle bar against the lower face of the plate 36, one such C-clamp being shown at 38 in Fig. 1. A suitable gasket may be provided between the members 31 and 36.

Means are provided for vertically raising and lowering the material collecting unit 3 alone, or the material collecting unit 3 and the cyclone separating unit 2, to provide access to the interior of the apparatus at the position of connection between any two of the three units I, 2, and 3. The means for this purpose may advantageously ycomprise a hoist device operatively associated with the units 2 and 3, `such as a Iflexible chain or rope 4I, secured to the material collecting unit 3 as shown at 42. From the point of connection 42, the chain 4I extends upwardly, over an idler sprocket or pulley 43, then downwardly over an actuating sprocket or drum 44, thence over an idler sprocket or pulley 45, and upwardly to the connection 42.

I prefer to provide two such hoist devices, one

at each side of the apparatus, as indicated in Fig. 2. To provide for simultaneous operation thereof, the two sprockets 44 which serve as drive sprockets for the chains 4I, are shown as mounted upon a shaft 46, and a crank 41 is operatively connected to said shaft through worm gear means 48. It is understood that the particular form of hoisting means shown is merely illustrative, and that any other suitable means may be employed for vertically raising and lowering the material collecting unit 3 and/or the cyclone unit 2.

Means are preferably also provided for guiding and laterally positioning the units 2 and 3. For this purpose, I have shown four vertical guide rods 5I positioned adjacent the respective corners of the apparatus. Said guide rods may be secured at their upper ends to the fixed supporting bars I4, as shown at 52, and at their lower ends to diagonal frame members 53, which are secured to the lower horizontal frame members I3. It will be understood that the guide rods 5I extend throughopenings, not shown, in the angle bars 22 at the upper end of the cyclone unit 2, in the plate 36 and bars 39 at the lower end of said unit and in the angle bars 31 at the upper end of the material collecting unit 3, the several members above mentioned slidably engaging said guide rods.

In the operation of the above containing `dust or apparatus, gas other suspended material is introduced through inlet connecton 6, and after separation of a substantial portion of the suspended material as hereinafter described, the clean gas is discharged through outlet connection 1, it being understood that the iiow of gas through the apparatus at a suitable velocity may be maintained either by natural draft or by artificial draft, as through the agency of a fan.

The gas supplied to inlet connection 6 enters the gas inlet Vchamber 4 and passes downwardly through the annular passages 21 and between the inclined vanes 3I which impart thereto a rapid whirling motion about the axes of the respective cyclone elements I6. The gas thus entering each cyclone element passes downwardly therein with a whirling motion, and then inwardly and upwardly through the outlet tube 26 of that element. The suspended material, or 4a substantial portion thereof, is thrown outwardly by centrifugal force within the cyclone outlets, and is carried downwardly along the walls thereof, and discharged through the restricted dust outlet openings 33 into the material collecting cham# ber 3, where it is deposited and whence it may be removed either continually or from time to time through the outlet opening at 32, it being understood that suitable means are provided for normally preventing outflow or inflow of gas or air through said opening. The clean gas discharged through the outlet tubes 26 passes through the outlet chamber 5 to the outlet connection 1. The operation of the above described apparatus, for the separation and collection of suspended material, is substantially the same as that described in United States Patent No. 1,909,184, and reference may be had to said patent for a more complete description of such oper,- ation.

It frequently becomes desirable to gain access to the interior of the apparatus, for the purpose of cleaning, inspection, repair, or replacement of parts.
